Specification of Letters Patent. Patented 11;, 1920;

Application filed. April 17, 1918., Serial No. 2 29,124.-

To all whom it may concern:

Be it known that 1, CHARLES M. EARL, a citizen of the United States, residin at Detroit, in the county of Wayne and tate of Michigan, have invented a new and useful Sealing Valve for Carbonated Beverage Containers, of which the following is a specification.

This invention relates to sealing valves for carbonated beverage containers, and is particularly adapted for use in association with the dispensing device disclosed in my copending application, Serial Number 225,908.

It is the object of the invention to facilitate the dispensing of carbonated beverages by providing a sealing valve upon the container wherein the beverage is held under gaseous pressure, and to adapt said valve to be automatically opened through the engagement therewith of a dispensing device associating a dispensing valve and an aerating chamber in a unitary relation.

This object is attained by the construction hereinafter described and illustrated in the accompanying drawings, wherein,

Figure 1 is a view in side elevation of the sealing valve applied to a container and as sociated with a suitable dispensing device.

Fig. 2 is a detail sectional view of the sealing valve member showing it unseated through engagement with a dispensing valve.

Fig. 3 is a view of the sealing valve mem ber disassembled from its stem.

In these views the reference character 1 designates a common type of container for holding carbonated beverages under gaseous pressure. The same is kept cold preferably by inserting it in a perforated inner receptacle 2 which is disposed. centrally within an outer receptacle 3, chopped ice being put into the space between the two receptacles. into the top of the container 1 there is screwed the stem of a valve casing 4, with the inlet of which there is connected a tube 5 depending into said container. A sealing valve member 6 within said casing is acted upon by a coiled spring 7 to hold it against an annular seat 8 formed upon the detach able cap 9 of the casing. Preferably the valve member 6 carries a packing ring 10 which provides the seat-engaging surface and insures against leakage. Said valve member is screw-threaded upon the lower end of a tubular stem 11 slidably mounted in an upward extension 12 of said cap and having aseri'es of ports 13' opening thereinto just above the valve member; As an additional safeguard against leakage" another packing ring 14 is seated against an annular flange 15 formed upon the stem above the ports 13, and a sleeve 16 is clamped by the valve member between the two packing rings to hold the same in place. Ports 17 are formed in said sleeve and register with the ports 13 of the stem when the parts are assembled. The tubular stem 11 is so proportioned in length that its upper end will project a slight distance above the extension 12 when the valve member 6 is seated. The extension 12 is threaded for engagement by the casing 18 of a valve 19, and said casing has an interior shoulder 20 which engages and depresses the end of the stem 11 to unseat the valve member 6 as the casing 18 is being engaged with said extension. Also as the casing 18 is being disengaged from said extension the valve member 6 will be moved to its seat by the spring 7.

The casing 18'is surmounted by an aerating chamber which has a unitary relation with said casing and its valve 19. This chamber comprises a base 2 1 preferably integral. with the casing 18, a top 22, and a cylindrical glass Wall 23 which is clamped between said top and bottom by bolts 24. lVithin said aerating chamber a pipe 25 rises and is adapted to discharge through a nozzle rotatively mounted upon its up er end and comprising radial arms 26. (due or more gas outlets 27 are provided in the top '22 and a discharge pipe 28 is formed integral with the bottom 21.

By employing the above described con struction it becomes possible to conveniently dispense a carbonated beverage from the same container in which it is transferred from the factory to the point of use. At the latter point the unitary dispensing valve and aerating chamber may be quickly applied, and the sealing valve thereby opened. The superiority of the automatically con trolled sealing valve over one which might be controlled by hand lies in the fact that the former requires no handle such as might be broken off or accidentally turned on while the container is in transit, and further in the fact that dispensing of the beverage may be expedited by eliminating necessity for manipulation of a sealing valve.

A considerable saving of time is also accomplished by the use of the aerating chamber within which the discharging beverage is freed from carbonaceous gas so that it will flow freely into the dispensing vessel and may be served Without Waiting for gas to escape, as is necessary When some such provision is not made.

What I claim is: i

In a sealing valve, the combination with a valve casing having a detachable cap portion,' of a sealing valve within said casing adapted to seat upon said cap portion, a

tubular stem for said valve providing an outlet from the easing means Within the casing yieldably urging said valve to its seat, and a dispensing valve detachably mounted upon said cap, controlling the discharge from said tubular stem and acting through said stem to unseat the sealing valve.

In testimony ivhereof I sign this'specification.

CHARLES'M. EARL.
